Since wireless continues to be a popular alternative to wiring your office, i thought a quick round up of current technologies would be appropriate.

In Summary:

Open Access - bad, anyone can watch your traffic or access your network as if they were plugged directly into your hub.

WEP - bad, can be cracked in minutes with the latest tools. Once the key is cracked intruder has access as if the AP was Open. Read your network traffic and access your network.

WPA - good, if configured properly with a strong key this will stand up to all but the most skilled attackers.

Now if the only equipment you have is WEP - then the risk can be mitigated. Change keys on a regular basis and encrypt all communication via ssl. Keep in mind though that you are running a very open system - so be aware of the information you are sending through the air.
